How to Solve the Boiler Room Plate Puzzle – Alone in the Dark

After leaving the Hateful Mound in chapter 2, it will be time to do your second plate puzzle, this time in the Boiler Room. This will be a similar process to the one in the Gallery Clock, but will be slightly more involved. In this guide, we will go through the steps on how to solve this puzzle.

Like the previous plate puzzle, in order to solve the one in the Boiler Room, you will first need to find two Broken Plates.

One plate will be in the room connecting to the south side of the Boiler Room — the one that is initially blocked off by steam. Once you find your way inside the room, speak with ‘Jeremy’, and after a short interaction, the Broken Plate will be on the floor.

The other plate will be in Cassandra’s Room. In order to get this one, however, you will first need to solve the padlock puzzle inside. If you need assistance with that, you can check out our guide here!

Now that we have both plates, we can take them to the Boiler Room — inserting them into the boiler will automatically start the puzzle. Like before, the idea will be to arrange the pieces to make a coherent picture. However, there are two key differences:

  • There are a total of 16 pieces you can move.
  • There is no static piece this time — all the pieces can and need to be moved.

The easiest way to go about this is to start with the four center pieces. You can clearly make out a building and a sun — make sure the building is standing upright on the lower left, and that the sun is shining above on the upper right. From here, you can use the fields around the building and the rays coming out of the sun as reference points.

This will make figuring out the outer plates easier. Pieces that look like they are part of the field will go to the bottom half, while the clouds will go to the upper half. The circular shape of the full plate will also help show if a piece will or will not fit to where you’re moving it at all. When you’ve moved everything correctly, the plate will look like the picture below:

The solution

Once all of the pieces are properly arranged, you will be taken out of the screen, and the boiler will make a loud noise. Interacting with the plate again will now initiate the Boiler Room Talisman Puzzle, which will be your next step in progressing with your search for Jeremy.
